UN chief Ban Ki-moon has slammed Israel’s “provocative” settlements, saying the attacks by Palestinians he condemns are a natural reaction to the occupation. This escalated into a war of words as the Israeli PM accused Ban of supporting terrorists.

Speaking before the United Nations Security Council, Secretary-General Ban said he was “deeply troubled” by new reports that the Israeli government has approved plans to build more than 150 new settlements, which he referred to as “provocative acts” by Jerusalem.

This and other activities, such as the declaration of 370 acres in the West Bank south of Jericho as “state land,” according to Ban, “are bound to increase the growth of settler populations, further heightening tensions and undermining any prospects for a political road ahead,” the UN said in a press release.

As he touched upon the volatile situation between the two states, Ban also condemned the growing number of vengeful attacks by Palestinians against Israeli citizens.

“Stabbings, vehicle attacks and shootings by Palestinians targeting Israeli civilians – all of which I condemn – and clashes between Palestinians and Israeli security forces, have continued to claim lives,” Ban said, adding that security measures are not going to help. “Palestinian frustration is growing under the weight of a half century of occupation and the paralysis of the peace process.”

Ban said that the attacks by Palestinians are a “human nature” reaction to occupation, which oppressed people have been carrying out throughout the ages, and “often serves as a potent incubator of hate and extremism.”

He also noted “the profound sense of alienation and despair driving some Palestinians – especially young people.”

“Continued settlement activities are an affront to the Palestinian people and to the international community. They rightly raise fundamental questions about Israel’s commitment to a two-state solution,” he said.

Ban used his bully pulpit to urge Israel and Palestine to “act now to prevent the two-state solution from slipping away forever,” warning that the peace process would require “difficult compromises”.

The UN chief’s remarks triggered a swift reaction from the Israeli Prime Minister, however, who accused Ban of essentially supporting terrorists.

“The secretary-general’s remarks provide a tailwind for terrorism. There is no justification for terrorism. Those Palestinians who murder do not want to build a state, they want to destroy a state and they say this openly,” Benjamin Netanyahu said.
